Have you tried lowering the 802.11 transmission retry count to 0? In 802.11, a transmitter has to receive acknowledgement of the last packet it sent in about 10 microseconds, or else it will retransmit it. An 802.11 radio is typically set to retransmit about 5 times before it gives up. On a 10 mile link, the roundtrip time is about 100 microseconds, so ACKs are coming 90 microseconds too late. Every packet may be retransmitted 5 times, which really cuts into your available bandwidth. It may also play havoc with TCP, cutting the bandwidth even more.
